To all whom it may concern:

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States, residing in the city of Philadelphia, county of Philadel phia, and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing Devices, of which the following is a full, clear, and exact specification.

My invention relates to dyeing devices and refers particularly to those devices suitable for dyeing wound fabrics with dyeing liquids. One object of my invention is a device whereby a series of wound fabrics may be subjected simultaneously to equal and uniform treatment with dyeing liquids.

Another object of my invention is a device in which fabric of any width may be subjected to equal and uniform'treatment with dyeing liquids.

Another object of my invention is a device in which a dyeing liquid may be passed in opposite directions through a series of wound fabrics to produce even and uniform results. Another object of my invention is a device in which wound fabric may be maintained in a fixed position during the passage of a liquid through it in opposite directions.

Another object of-iny invention is a device in which the condition of the fabric may be determined without opening the device, interrupting the operation or disturbing the fabric.

These and other objects of the device of my invention will be evident upon a consideration of my specification, drawings and claims.

A number of difiiculties present themselves in the dyeing of wound fabrics. All portions of the fabric must receive equal treatment in order that the interior, exterior and edges of the fabric may be uniform, equal penetration must exist in all parts, and the device must be capable of treating fabric of varying widths. In addition to these requirements, it is advantageous to treat a number of wound fabrics simultaneously in order to save time and labor and insure uniformity of results. Further, it is essen tial that the condition of the treated'fabric be capable of judgment from time to time without disturbing the fabric or interruptingthe operation.

The device of my invention accomplishes all of these desirable results and presents a method whereby number of. fabrics of varying widths may be dyed equally and uniformly in a simple, rapid and economical manner, and the treated condition observed without interrupting the operation or disturbing the fabric.

'In order that all parts of the wound fabric may be treated equally and evenly by a liquid, it is essential that the fabric be under a uniform pressure and freefrom disturbance during the treating operation. In order to produce this desired uniform pressure throughout the fabric roll, I maintain the fabric roll, under pressure, between foraminous members supported by resilient elements, thus compensating for any varying thickness or density of the roll.

In the particular form of the device of my invention, as shown in the accompanying drawings, similar parts are designated by similar numerals Figure 1 is a diagrammatic side plan of one form of my device showing one testing device.

Fig. 13 is an enlarged vertical section of a testing device. The particular form of my device as shown in the accompanying drawings comprises a series of cylindrical members 21, 21, each of which acts as a dyeing chamber. The flanges 21 21 of the chambers 21, 21, are attached to the flange 22 of the bottom 22 by means 9;- the bolts 23, 23. The walls of the chambers 21, 21 are integral with the 22 and are integral with the plate 25, the,

latter being attached to the Wall 26 of the chamber 27. The top portion of each coir duit 24 is extended into the angular annular member 28. The bottom 26 is connected to the pipe 29 carrying the valve 30 and the bottom 22 is connected to the pipe 31 carrying the valve 32. The pipes 29 and 31 converge into the pipe 33 which is connected to the discharge chamber of the pump 34. The receiving chamber of the pump 34 is connectedto the pipe 35 carrying the valve 36 and to the pipe 37, carrying the valve 38 connected with the bottom of the reserve tank 39. A pipe 40, carrying the valve 41,

' foraminous cylindrical member 54, formed 'in four parts, is spaced from the member 52 by the springs 55, 55, positioned by the pin 56, one end of which is within a recess in the member 52 and the other end of which is within'a recess in the member 54. The member 54 comprises a series of parallel pyramidal members 57, 57 with the longitudinal openings 58. 58 between them. Within the hollow cylindrical member 52 is an imperforate member 59 having the upwardly and downwardly converging ends 60 and 61, and being supported on the members 50, 51, by the supporting arms 62, 62. The reel thus formed is capable of having fabric wound thereon. In order to compress fabric Wound upon the member 54 and to prevent it from being displaced during the dyeing operation, I employ a foraminous cover 64, formed in four parts, the cover 64 having inwardly extended longitudinal blades 65, 65. A series of rods 66, 66, each carrying a flange end- 67, is slidable through the member 64 and held from displacement by the nuts 68, 68. A spring 69 abuts upon the flange 67 and the member 64.

An annular member 70 abuts upon the member 50 and; is slidable thereon. The upper apex of the member 70 fits within a corresponding recess in the lower portion of thea'nnular member 71 which also abuts uponthe member 50am is slidable thereon.

a suitable paeki' igmami or gasket- 72 is situated Within the recess of 71 in order to form a tight joint between the members 70 and 71. A series of threaded bolts73, 73, pivoted to the member 70 at 74, 74 are capable of placement through slots 75, 75 in the extensions 76, 76 of the member 71, and by means of the wing nuts 77, 77, the mem bers 70 and 71 can be brought into, and maintained in, close abutment.

An angular annular member 7 8, abuts upon the member 51 and is slidable thereon. A series of threaded bolts 7 9, 79, pivoted to the member 78 at 80, 80 are capable of placement through slots in the extensions 81, 81 of the member 51, and by means of the wing nuts 82, 82, the members 78 and 51 can be brought into and maintained in close abutment, the packing 83 causing a tight joint between them.

Fixedly carried by the arm 84 of the member 70, and the arm 85 of the member'7 8, is a series of extended members 86, 86, the other ends of which are integral with a series of concentric annular members 87, 87 slidable over each other. Each extended member 86 carries a spring 88 abutting upon the members 84 or 85, and one of the members'87. The inner member 87 abuts upon and is slidable over the foraminous cylinder 54, closing some of the openings therein. I 5

The members 70 and 78 carry a series of extended arms 89, 89 each having a slot 90. Placeable within each pair of arms 89, 89 in alinement with each other are rods 91, 92, connected by means of a turn-buckle 93.

An annular member 94, hinged at 95, abuts upon the flanges 67 67 and is capable of being compressed upon said flanges and held in position by means of the wing'bolts 96, 96 passing through the flanges 97, 97 of the member 94.

A testing device, as shown in detail in Fig. 13, is attached to each dyeing chamber of the larger device by means of wing bolts 101, 101. These testing devices are similar to the larger device, similar parts being designated by prime numerals. The chamber 102 is connected to the chamber 102 by means of the pipes 103, 103 carrying the valves 104, 104. The chamber 105 is connected to the chamber 106 by means of the pipe 107 carrying the valve 108.

The operation ofthe device is as follows, assuming that the chamber tops 109, 109 are removed and the reels taken out from each dyeing chamber The foraminous annular member 54, with its extended members 56, 56, is placed around the foraminous cylinder 52, fabric 100 is wound around the foraminous member 54, the member 64.with its extended members 65, 65 is placed around the cloth, the members 65, 65 abutting thereon and the member 94 placed around the member '64, The members 78 and .51 are then brought into close abutment by means of the wing bolts 82, 82. The series of rods 91, 91, 92, 92 are placed Within the slots Within the arms 89, 89 and the turn buckle turned until the members 87, 87 abut closely upon the edges of the Wound fabric. The members 71 and are then brought into close.

abutment by means of the Wing bolts 77, 7 7. A reel thus Wound and assembled is placed in each. dyeing chamber, the lower end of the member 51 resting in the annular recess formed by the member 28 to form a tight joint. The top 109 is then replaced and fastened by the bolts 101, 101, the up per portion of the member 50 fitting Within a recess of the top 109 to form a tight joint. Each testing device, is assembled in a similar manner.

All of the valves are now closed, With the exception of valves 86, 30 and 13, and the pump 3% started. The liquid noW passes from the dissolving tank, not shown, through the pipe 35, the pump 34, pipes 33 and 29, the bottom chamber 27 and pipes 24:, 24 into the interior of the reel, whence it is forced outwardly through the foraminous cylinders 52 and 5ft, the fabric 100, the foraminous cover 64; into the chamber 102, and thence through the chamber 110 and the pipes 81 and 42 into the reserve tank 39. When suflicient liquid has been introduced into the reserve tank, valve 36 is closed and valve 38 is opened, thus allowing a continuous circulation of the liquid in the direction above described. At the same time, the liquid passes in a similar manner through each testing device.

When it is desired to reversethe flow of liquid, valves and 13 are closed and valves 32 and 45 are opened. The liquid novv passes through the pipes 33 and 31 and chamber 110 into the dyeing chambers exterior of the reel and thence inwardly through the foraminous members and the fabric into the interior of the reel and thence through the pipe 2 1, the chamber 27 and the pipes 29, 41 1 and 42 into the reserve tank for continuous circulation. At the same time the liquid passes similarly through the testing devices.

When it is desired to examine the fabric in a testing device, the valves 1041, 104; and 108 are closed, the top 109 removed and the reel removed.

WVater may be admitted through the pipe l0 and the fabric Washed by a process as above described. Y
